I have 2D arrays of numeric data and I would like to calculate the vector gradient of these arrays.
I would like to achieve something like the 'gradient' function of MatLab: https://www.mathworks.com/help/matlab/ref/gradient.html
In my understanding the 'Grad' function of Mathematica works on expressions of functions. I had a look at other functions but I didn't seem to find anything appropriate. I tried searching on the stackexchange, I apologize if this is trivial or a duplicate, I would really appreciate it if someone could point me in the right direction.
Thank you very much.
